"If you make "don't get stuck" a motto, you can easily imagine people skipping over difficult problems and not thinking about a good solution."

It is also important to define, what "getting stuck" means. For the research the alpha performers where the ones who fulfilled the goal quickest. If you switch the point of view from the teachers to the learning student, instead of fulfilling the requested goal quickest, you might follow an interesting problem that you discovered on the way. Is that getting stuck? No! It is following your own path of learning which is a very effective method. It does not look best to the teacher, but it can be very good for the learning student.

Asking your own questions and answering them is an important part of a learning process. It also makes you independent, so you don't simply do most efficiently what someone told you to do.
